Your "modern pig" A.K.A, the Yamaha Ténéré 700, has ABS. The ABS needs small sensors to monitor wheel slippage, so they are vital for your safety - and at the same time, the rear one is so easily damaged due to its location.
 
Save yourself the risk and headache of a damaged sensor on your next trip with this small but effective guard. This simple protection bracket will protect it from side impacts, rocks, and flying debris while staying lightweight and discreet. 
 
It's made of hardened aluminum with a black finish to match your brake calliper colour and installs in a jiffy with the included hardware.
